Blood in stool

I've had frequent bowel movement for many years.  For years I had blood in the stool occasionally (maybe once a month) but lately I find blood almost every other days.  The amount of blood is small, not enough to make the toilet bowl red but I can see it on the toilet paper when I wiped.  I had colonoscopy 3 years ago but it was normal.  I would like to know what else should I do at this point?

Hi,
Blood in stools could be due to many reasons like hemorrhoids, fissures, polyps, IBD, diverticulosis and malignancy.
If the blood is bright red  then the possible causes are hemorrhoids and fissures which are lesions lower down in the anal canal.
If the blood is darker or if there is associated mucus, then the source of bleeding is high up in the large bowel.
